Lessor BOC Aviation has placed an order for single- and twin-aisle Boeing aircraft valued at $8.8 billion at list prices.

The Singapore-based lessor has ordered 50 Boeing 737 MAX 8s, 30 Next-Generation 737-800s and two 777-300ERs. The contract is the largest in BOC Aviation’s 20-year history.

BOC Aviation is owned by Bank of China, which describes itself as the largest aircraft financing bank in the world.

“Following the successful placement of the 50 Next Generation 737 aircraft that we ordered in 2006, this is a continuation of our commitment to be responsive to airline customers which are expanding or replacing older fleets,” BOC Aviation MD and CEO Robert Martin said, adding “BOC Aviation expects healthy demand for the Next Generation 737 and 737 MAX variants in the next seven years.”
